#raku-beginners: korvo: Hi! I’m trying out Raku in stead of META II for a toy compiler. (5 minutes later) korvo: I’m merely trying to compile a little expression language because my angle of repose has slightly increased, and multiple folks have recommended Raku for parsing and lightweight compilers. (20 minutes later) korvo: [T]hanks for aContinue reading “Day 15 – An expression language for Vixen”

Day 14 – Taming Concurrency
Hello everyone and a merry advent time! Today I’d like to show case a neat little mechanism that allows building concurrent applications without having to worry about the concurrency much. I’ve built this tool as part of the (yet to be released) Rakudo CI Bot. That’s a middle man that watches GitHub for things toContinue reading “Day 14 – Taming Concurrency”
Day 13 – Christmas Crunching Part II
Christmas is nearly on us, 10 shopping days to go. Things at the pole were gathering pace, with so much left to do. Rudolph (him again) was pacing up and down, mashing his cheroot. He cast his mind back to the App::Crag calcs he had done last time – sure all the distances, times andContinue reading “Day 13 – Christmas Crunching Part II”
Day 12 – Mathematician’s Yahtzee
Santa was playing and losing yet another game of Yahtzee with Mrs. Claus and the elves when a thought occurred to him: why don’t you get points for rolling the first 5 digits of the Fibonacci sequence (1, 1, 2, 3, 5)? For that matter, why isn’t there a mathematician’s version of Yahtzee where you get points for rollingContinue reading “Day 12 – Mathematician’s Yahtzee”
Day 11 – Raku To The Stars
Datastar is a hypermedia systems library in the same tradition as htmx, Unpoly, Alpine AJAX, and Hotwire‘s Turbo. These libraries are generally Javascript/Typescript bundles that utilize the HTML standard to allow you to declaratively write AJAX calls or JS-powered CSS transitions as HTML tag attributes instead of hand-writing Javascript. @librasteve has been working on AirContinue reading “Day 11 – Raku To The Stars”
Day 10 – Santa’s Finance Department
Cron Meets Raku The Finance Department’s computers had been converted to Debian Linux with Rakuized software along with all the other departments at the North Pole headquaters, and its employees enjoyed the Windows-free environment. However, an inspection by a firm hired to evaluate efficiency practices found some room for improvement. Much of the work dayContinue reading “Day 10 – Santa’s Finance Department”
Day 9 – Monadic programming examples
This document provides examples of monadic pipelines for computational workflows in Raku. It expands on the blog post “Monad Laws in Raku” by including practical, real-life examples.
Day 8 – HARC The Herald Angels Sing
Rudoph had long wanted wanted to write a website – he longed to share his hobbies and opinions with all the children, so that they wouldn’t just think of him as a first class pilot and navigator. He knew about Raku and he had skim read some information about Cro and Humming-Bird. But, being quiteContinue reading “Day 8 – HARC The Herald Angels Sing”
Day 7 – Allowing for fewer dollars
Lizzybel had been taking a bit of vacation from all of the busy-ness in the corridors of North Pole Grand Central. While doing a small visit to the corridors, she ran into Nanunanu, one of the IT elves. Nanunanu was a bit worried, because they had not seen Lizzybel for a while. “Don’t worry”, said Lizzybel. “I’m just recharching my batteries aContinue reading “Day 7 – Allowing for fewer dollars”
Day 6 – Robust code generation combining grammars and LLMs
This document (notebook) discusses different combinations of Grammar-Based Parser-Interpreters and Large Language Models to generate executable code from Natural Language Computational Specifications.
